Precision Twist Drill 5995716 Cobalt Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 5995716 is a taper length cobalt drill bit designed for high-performance drilling in demanding industrial and trade applications. Built to Series M52CO specifications, it features a 135-degree split point and a web-thinned, tapered web configuration that promotes self-centering entry and reduces thrust force. The bit is finished with a gold oxide coating for added surface hardness and heat resistance. The straight cylindrical shank measures 0.2010 inches in diameter, matching the No. 7 wire gauge size. Licensed tradespeople and machinists working in metal fabrication, maintenance, and equipment repair will find this bit suited to production-level use.

This drill bit is built for cutting through a broad range of materials including alloy steel, carbon steel, stainless steel, hardened steel, cast iron, malleable iron, brass, bronze, high-strength bronze, copper, aluminum, aluminum alloy, magnesium, magnesium alloy, nickel, nickel alloy, cermet, graphite, and reinforced plastic. It is appropriate for both shop and field use where taper length reach is needed beyond what a jobber-length bit provides. The 6xD flute-to-diameter ratio and 3.625-inch flute length give added chip clearance in deeper bores. This is a right-hand cut, spiral flute bit conforming to ANSI standards.

Key Features

• Series M52CO cobalt construction for heavy-duty, high-heat cutting applications
• 135-degree split point with web thinning for self-centering starts and reduced walking
• Gold oxide coating adds surface protection and reduces friction during cutting
• Taper length at 6 inches OAL provides extended reach versus standard jobber bits
• Straight cylindrical shank at 0.2010 inches fits standard drill chucks without adapters
• Conforms to ANSI standards; rated for high-performance, heavy-duty use

Compatibility

Designed as an OEM-style replacement or direct-use taper length drill bit for No. 7 wire gauge applications in standard three-jaw drill chucks accepting a 0.2010-inch straight shank.

Installation Notes

Install in a drill press, mill, or hand drill with a chuck rated for the 0.2010-inch straight shank diameter. Secure the shank fully and verify chuck tightness before operation. Use cutting fluid or coolant appropriate for the workpiece material to extend bit life, particularly when drilling stainless steel or hardened steel. Follow applicable shop safety standards and wear appropriate PPE including eye protection during all drilling operations.
